It has a degree of 90* * * * *No, it does not. It has 180 degree rotational symmetry.
A rectangle has rotational symmetry of order 2. This means it can be rotated 180 degrees around its center and still look the same, as well as being symmetrical at 0 degrees (the original position). However, it does not have symmetry at 90 or 270 degrees, unlike a square, which has rotational symmetry of order 4.
No - a pentagon has 120 degree rotational symmetry.
No, it does not.

If you mean "Does it have a rotational symmetry", the answer is "Yes." there is a 180 degree rotational symmetry.
A line has 180 degrees rotational symmetry.
A rectangle has rotational symmetry of order 2. This means it can be rotated 180 degrees around its center and still look the same, as well as being symmetrical at 0 degrees (the original position). However, it does not have symmetry at 90 or 270 degrees, unlike a square, which has rotational symmetry of order 4.
No - a pentagon has 120 degree rotational symmetry.
No, it does not.
yes
Yes; 180 degrees.
Yes, a square has rotational symmetry. It has rotational symmetry of order 4, which means it can be rotated by 90 degrees, 180 degrees, and 270 degrees to coincide with its original position.
A parallelogram - including rhombus and rectangle - has 180 degree symmetry. A square has 90 deg.
A two-fold symmetry has a 360 degrees rotation. A three-fold rotational symmetry, on the other hand, has 120 degrees, and on a horizontal axis, a symmetry has 180 degrees.
A shape with a rotational symmetry order of 2 appears the same after a rotation of 180 degrees. Common examples include a rectangle and an isosceles triangle. In these shapes, rotating them halfway around results in the same appearance as the original position.
